I thought I'd take a more detailed look at the log of the last occurrence, but nothing was obvious. It's as though ASSP at some random time decided to not to answer SMTP requests. All ASSP does is its hourly housecleaning. Stopping ASSP with its web interface fixes the problem, because I have a watchdog up to restart ASSP if its process is not present.
I have no way of knowing if this is the result of a DoS attack crashing part of ASSP, or if it's something internal to ASSP.
